Kohakuiro no Hunter

Long ago, on a rusty, reddish planet floating in space, deep within its uncharted jungles, lay the Novastone Ore—a mineral said to hold immense energy.
Dreaming of striking it rich, people rushed to the planet, scrambling to claim the veins of ore for themselves.
But in this remote, untamed frontier—a place some called a "demonic realm"—what awaited them was something far beyond human comprehension.
Monsters.
Beings that defied reason.
——————Pure calamity.
